The utility model is characterized in that the utility model comprises a fixed cutting plate, a rotate cutting plate, a stop dental plate, an eccentric propelling rack combination, a handle locking switch, a movable handle and a static handle and the like, wherein, the eccentric impelling rack therein consists of an eccentric propelling plate, an arc rack and a connecting pin; the scissor plate is driven by the arc rack by rack gearing, which belongs to ratchet propelling structure; the handle locking switch consists of a locked switch plate, a fixed axle pin and a torsion spring, and the opening and closing of the movable handle bar can be easily and conveniently operated.

Description

A kind of portable cable is cut

Technical field the utility model relates to the portable cable that can open fast, pin of small dimension cable in a kind of shearing the and one-hand operation and cuts.

The present small-sized cable of background technology cuts that the fixed handle of setting is opened, locking device, must one during operation holding cable cuts, operation is opened, pinned to another hand, inconvenient, and after this device uses a period of time, because the phenomenon that fixed handle is not opened, be can't lock or pins voluntarily can appear in wearing and tearing, brings a lot of troubles to the user.Present small-sized cable is cut and adopted linear pattern to advance tooth bar, advances hour rack and tooth plate to have only a tooth engagement, and is stressed big, causes advancing tooth bar and tooth plate to damage easily, influenced useful life.

Summary of the invention the utility model provides a kind of improved portable cable that is used for shearing small dimension cable and one-hand operation to cut, and adopts the eccentric rack combination that advances, and can reduce the damage that advances tooth bar and tooth plate, has prolonged useful life; Be provided with the quick locking switch of handle, that can singlehanded carry out fixed handle opens, pins operation.The technical solution of the utility model is: a kind of portable cable is cut, mainly by fixing knife plate, revolve scissors plate, retaining tooth plate, eccentric rack combination, handle locking switch, fixed handle, the static handle etc. of advancing and form.Revolving scissors plate excircle is profile of tooth, constitute the cylindrical tooth plate, revolving the scissors plate links to each other with fixing knife plate by the pivot pin screw, the retaining tooth plate links to each other with fixing knife plate by fixing pivot pin, the eccentric rack combination that advances is by eccentric push pedal, arc-shaped rack, connecting pin is formed, arc-shaped rack is the inner concave shape arc rack, can fully mesh with the tooth plate that revolves on the scissors plate excircle during work, overcome the drawback that tooth bar and tooth plate damage easily, prolonged the useful life that cable is cut, the handle locking switch is by the locking switch plate, fixing pivot pin, torsion spring is formed, and the locking switch plate can be operated with opening the closure of fixed handle under the effect of torsion spring fast.Static handle is fixedlyed connected with fixing knife plate, and fixed handle is via being connected with fixing knife plate by pivot pin and eccentric push pedal with its fixedly connected eccentric shaft seat board.During use, reciprocally swinging fixed handle, thereby the motion of the eccentric propelling of drive rack combination revolve the scissors plate by arc-shaped rack by tooth engagement drive and make circular motion, are the ratchet-advance structure.Along with the motion of revolving the scissors plate, itself and fixedly knife plate close up gradually, thereby finish the function of shearing cable.By such scheme, the utility model provides a kind of portable cable simple to operate, easy to carry, that can simple and directly open and pin handle apace to cut.

Structural representation when Fig. 4 is in locking state for handle locking switch in the utility model.

Among the figure: 1 pivot pin screw 2 fixedly knife plate 3 revolves the fixedly fixing pivot pin of pivot pin 10 support springs 11 eccentric push pedal 12 eccentric shaft seat boards 13 pivot pins 14 torsion springs 15 locking switch plates 16 of scissors plate 4 retaining tooth plates 5 static handles 6 fixed handles 7 arc-shaped racks 8 connecting pins 9

Embodiment as shown in Figure 1 and Figure 2, the utility model mainly by fixing knife plate 2, revolve scissors plate 3, retaining tooth plate 4, eccentric rack combination (being made up of eccentric push pedal 11, arc-shaped rack 7, connecting pin 8), handle locking switch (by locking switch plate 15, fixedly pivot pin 16, torsion spring 14 are formed), static handle 5, the fixed handle 6 of advancing formed.Revolving scissors plate 3 excircles is profile of tooth, constitute the cylindrical tooth plate, inboard curved portions is a shear blade, revolves scissors plate 3 and links to each other with fixing knife plate 2 by pivot pin screw 1, and fixedly the inboard curved portions of knife plate 2 is a shear blade, retaining tooth plate 4 links to each other with fixing knife plate 2 by fixing pivot pin 9, retaining tooth plate 4 blocks the cylindrical tooth plate that revolves scissors plate 3 under the effect of support spring 10, make to revolve scissors plate 3 and can not move clockwise, if Press presses retaining tooth plate 4, can remove screens; Figure 3 shows that the eccentric rack combination that advances, form by eccentric push pedal 11, arc-shaped rack 7, connecting pin 8, arc-shaped rack 7 is the inner concave shape arc rack, can fully mesh with the cylindrical tooth plate that revolves scissors plate 3 during work, the multiple tooth while is stressed, the stressed of each tooth significantly reduced, overcome the drawback that tooth bar and tooth plate damage easily, prolonged the useful life that cable is cut.Static handle 5 is fixedlyed connected with fixing knife plate 2, and fixed handle 6 is via being connected with fixing knife plate 2 by pivot pin 13 and eccentric push pedal 11 with its fixedly connected eccentric shaft seat board 12.During use, open fixed handle 6, eccentric shaft seat board 12 rotates, driving eccentric push pedal 11 moves down, and then drive arc-shaped rack 7 is moved downward to home position, be close to the cylindrical tooth plate that revolves scissors plate 3, revolve scissors plate 3 and stop original position, closed fixed handle 6 owing to the effect of retaining tooth plate 4, eccentric shaft seat board 12 backward rotation, drive eccentric push pedal 11 and move up, and then drive arc-shaped rack 7 and move up, and drive by the tooth engagement and to revolve scissors plate 3 and do motion counterclockwise, reciprocally swinging fixed handle 6, revolve scissors plate 3 and do motion counterclockwise continuously, it closes up gradually with fixing knife plate 2, thus the shearing cable; The handle locking switch is by locking switch plate 15, fixedly pivot pin 16, torsion spring 14 is formed, under the free state, as shown in Figure 2, locking switch plate 15 outwards flicks under the effect of torsion spring 14, fixed handle 6 can freely swing, when pinning fixed handle 6, as shown in Figure 4, close up fixed handle 6 and static handle 5, simultaneously press locking switch plate 15 downwards, make the flange of locking switch plate 15 block recess on the eccentric shaft seat board 12 of fixedlying connected with fixed handle 6, this moment release handle, fixed handle 6 promptly is lockable, when opening handle, as long as hold fixed handle 6 and static handle 5 with a firm grip, eccentric shaft seat board 12 is moved counterclockwise, under the effect of torsion spring 14, the flange of locking switch plate 15 outwards flicks from the recess of eccentric shaft seat board 12, and fixed handle 6 can freely swing.
